Voice Reversals and Syntactic Structure: Evidence from Hittite

We address the relationship between syntactic valency and voice morphology in Hittite (Anatolian, Indo-European), focusing on cases where active syntax is expressed using non-active morphology, and vice versa. We argue that apparent “mismatches” between syntax and morphology are strictly a morphological rather than a syntactic phenomenon (contra Alexiadou et al. 2015; Grestenberger 2018). Our study highlights voice “reversals” — i.e., cases in which the expected mismatch disappears and morphological and syntactic valency match. We determine that such reversals correlate with morphological locality, and cannot be derived by hierarchical factors. Our findings provide a novel argument for a uniform syntactic structure of voice (Wood 2015; Wood & Marantz 2018).
